Title: Solid oxidation catalysts
IPC: B01J27/19
Filed: 1961-01-10
Abstract: An oxidation catalyst contains in combination (a) an oxide of bismuth, (b) an oxide of tungsten and/or molybdenum such that the atomic ratio of Bi to W and/or Mo is between 1 and 25 atoms per 10 atoms of Mo and/or W and (c) arsenic oxide in an amount corresponding to between 0,1 and 6 atoms of As per 10 atoms of Mo and/or W. Additionally the catalyst may contain phosphorus silicon and/or sulphur in amounts up to 5 atoms per atom of Mo and/or W.  In preparing the catalyst use may be made of a heteropolyacid containing phosphorus, silicon and/or boron. Bismuth may be replaced in any amount up to approximately 50 atoms per cent by one or more of the elements lead, silver tin and manganese.  The catalyst may be supported on an inert carrier, e.g. silica sand, silicon carbide or broken firebrick.  Use may also be made of inert diluents such as colloidal silica, ball clay and graphite.  Examples are given.ALSO:Catalysts containing in combination (a) an oxide of bismuth, (b) an oxide of tungsten and/or molybdenum such that the atomic ratio of Bi to W and/or Mo is between 1 and 25 atoms per 10 atoms and (c) arsenic oxide in an amount corresponding to between 0.1 and 6 atoms of As per 10 atoms of Mo and/or W may be used in the oxidation with molecular oxygen of alkynes, olefines and diolefines, alkyl aromatic hydrocarbons, alcohols, aldehydes, furans, alkylthiophenes, terpenes and many of their analogues having common substituted groups.  Temperatures of 300 degrees to 600 degrees, pressures of 0.7 to 7 atmospheres and space velocities of 100 up to 3000 volumes of reactant per volume of catalyst per hour, are generally used.  Examples describe the conversion of propene to acrolein and butenes to butadiene. Reference is also made to the oxidation of acetaldehyde to acetic acid.

Abstract: 413,647. Wireless transmitting and receiving systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London.-(Assignees of Crosby, M. G.; Riverhead, Long Island, New York, U.S.A.) Jan. 17, 1933, No. 1554. Convention date, Jan. 23, 1932. [Class 40 (v).] In a radio transmission system of the phasemodulation type, modulation is effected by tapping off from an artificial line two carrier voltages in different phase, varying the amplification of these voltages in accordance with the signal, and combining the amplified voltages. The system also includes suitable receiving circuits. Modulating circuits. The carrier wave from the source 2, Fig. 1, is picked up in two separated phases by tappings 22, 24 on the artificial line 4, and is transferred to the inner grids of a pair of valves 14, 16. The plate circuits of these valves are jointly coupled to an amplifier or frequency-multiplier 32 which feeds the aerial 34. The amplification of the valves 14, 16 is controlled by applying the modulating signal in phase opposition to their outer grids 28, 30 ; this being effected by connecting these grids to the plates of a push-pull pair of valves 26 the grid circuits of which are coupled to the microphone 24. The carrier waves are added vectorially in the transformer T, and as their respective amplitudes are varied by the signal, the phase of the resultant also varies with the signal. Current-limiting devices may be employed to eliminate amplitude modulation. The degree or depth of phase modulation may be increased by multiplying the frequency of the modulated wave before emission. Receiving circuits. The received wave is preferably reduced in frequency by heterodyne apparatus 44, Fig. 5, and after amplification the pure carrier is selected by a filter 48 and passed to a limiter 50, phase-adjuster 56, amplifier 60 and detector 62. The sidebands pass through an amplifier 52 to the detector 62. The phase-adjuster 56 gives approximately 90 displacement to the carrier and the detector 62 thus receives and detects an amplitude-modulated wave. Instead of isolating the carrier, a synchronous local oscillator may be used. When a pair of detectors in push-pull relation is used (Fig. 8 not shown), the pure carrier is applied to their grids in phase opposition, and the phase-modulation components in phase agreement.
